And a 3.07 is really too tall for the types of driving I encounter - too tough on the main bearings.
Very important point few appreciate. While the engine might pull a very tall gear, the main bearings don't like heavy loads at low RPMs.
Back in the day of three-speed trannnies, the small block Chevy never had main bearing problems. Once computers and lockup torque converters enabled pulling hard up hills at sub-2,000 RPMs, main bearing problems were the result.
